摘　　要：可燃物含水率大小决定森林燃烧的难易程度。利用中科院长白山定位站提供的气象数据,通过可燃物含水率与气象因子的相关分析,筛选预测因子,并通过多元一次回归分析建立可燃物含水率与气象因子关系模型。结果表明,林内温度、相对湿度、降雨量、连续无降雨日数与可燃物含水率相关性较强,经数学检验,可燃物含水率模型模拟效果良好。The moisture level of combustibles determines the difficulty of forest burning.In this paper,the daily meteorological data provided by Research Station of Changbai Mountain,Chinese Academy of Sciences and combustibles moisture were used to explore the relationship between combustibles moisture and meteorological factors and also established a model by multivariate regression.The results showed that the temperature inside forest,relative humidity,rainfall amount,continuous absent rainfall days were related with combustibles moisture.The prediction model fit well after statistical test.
